Decision Making ProcessDecision Making Process Managers usually make decisions by
following a four-step process (a.k.a. thescientific approach)1. Define the problem (or opportunity)2. Construct a model that describes the real-
world problem3. Identify possible solutions to the modeled
problem and evaluate the solutions4. Compare, choose, and recommend a
potential solution to the problemCopyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall1-14

Decision making is difficult, becauseDecision making is difficult, because Technology, information systems, advanced search
engines, and globalization result in more and morealternatives from which to choose
Government regulations and the need for compliance,political instability and terrorism, competition, andchanging consumer demands produce moreuncertainty, making it more difficult to predictconsequences and the future
Other factors are the need to make rapid decisions,the frequent and unpredictable changes that maketrial-and-error learning difficult, and the potential costsof making mistakes

DSS as an Umbrella TermDSS as an Umbrella Term The term DSS can be used as an
umbrella term to describe anycomputerized system that supportsdecision making in an organization E.g., an organization wide knowledge
management system; a decision supportsystem specific to an organizational function(marketing, finance, accounting,manufacturing, planning, SCM, etc.)

architectures, tools, databases, analyticaltools, applications, and methodologies
Like DSS, BI a content-free expression, so itmeans different things to different people
BI's major objective is to enable easy accessto data (and models) to provide businessmanagers with the ability to conduct analysis
BI helps transform data, to information (andknowledge), to decisions and finally to action

A Brief History of BIA Brief History of BI The term BI was coined by the Gartner
Group in the mid-1990s However, the concept is much older
1970s - MIS reporting - static/periodic reports 1980s - Executive Information Systems (EIS) 1990s - OLAP, dynamic, multidimensional, ad-hoc
reporting -> coining of the term “BI” 2005+ Inclusion of AI and Data/Text Mining
capabilities; Web-based Portals/Dashboards 2010s - yet to be seen

The Architecture of BIThe Architecture of BI A BI system has four major components
a data warehouse, with its source data business analytics, a collection of tools for
manipulating, mining, and analyzing thedata in the data warehouse;
business performance management (BPM)for monitoring and analyzing performance
a user interface (e.g., dashboard)

The Benefits of BIThe Benefits of BI The ability to provide accurate information
when needed, including a real-time view ofthe corporate performance and its parts
A survey by Thompson (2004) Faster, more accurate reporting (81%) Improved decision making (78%) Improved customer service (56%) Increased revenue (49%)

regardless of its name or nature, is to assistmanagement in solving managerial or organizationalproblems (and assess opportunities and strategies)faster and better than possible without computers
Every type of tool has certain capabilities andlimitations. By integrating several tools, we canimprove decision support because one tool can provideadvantages where another is weak
The trend is therefore towards developinghybrid (integrated) support system
